摘要
从致牛烂蹄病的稻草中分离的弯角镰孢菌菌株(Fusarium camptoceras)于1988年和1991年分两批接种玉米中,培养物用乙腈:水(3:1,v/v)提取,正已烷脱脂,Florisil色谱柱净化,经净化的提取液经电子捕获气相色谱(GC-ECD)、薄层色谱(TLC)分析和气相色谱-质谱联用(GC-MS)鉴定,证实了弯角镰孢菌可同时产生多种单端孢霉烯族化合物。弯角镰孢菌能同时产生这些代谢物,在国内外未见报道。
Corn cultures of Fusarium camptoceras isolated from the rice straw causing the disease of Fescue foot were analysed with TLC, GE-ECD and GC-MS. Several trichothecenes including nivalenol (NIV), fusarenon-X (F-X), scirpentrol (SCP), 7-deoxynivalenol (7-DON), 3-acetoxyscirpentriol (3-ASCP), 4-acetoxyscirpentriol (4-ASCP), 3-acetyldeoxynivalenol (3-ADON), 7-acetyldeoxynivalenol (7-ADON), 4,15 diacetylnivalenol (4,15-DANIV), 7,8-dihydroxydiacetoxyscirpenol (DOHDAS), etc. had been identified by GC-MS. No butenolide and zearalenone were found in these cultures. This is the first report about these (?)richothecenes produced by Fusarium camptocern. These trichothecenes may be a caustive factor of the disease of fescue foot.
